WINDOW SHADE GUIDE Filed Dec. 11, 1946 I nuentor AWTHUR BARON PatentedMay 16, 1950 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates generally to window shade devices, and moreparticularly to a combined guide and stop member for window shades,adapted to be installed in pairs, one on either side of the shade andsecured to the Window casing.

It is well understood that other devices have been developed and usedfor the same general purposes as this present invention, for example, awindow shade stop which is the subject matter of a patent issued toStich under #'l,806,373, in which a single slot is provided to guide thewindow shade. This device, in common with other devices of likecharacter, has the disadvantageous tendency to bind on the window shade,causing the window shade to loop above the stop member, especially whenthe device works loose or free enough to turn on the supporting screw,it being understood that all these devices are subject to considerableimpact and strain placed thereupon by the shade in normal usage.Furthermore, devices of this character heretofore developed have beenvery limited in the application thereof to different types of windowcasings.

It is an object of this invention, therefore, to provide a doubleslotted guide and stop member which, in functioning as a guide member,will have a greatly lessened tendency to work loose from the windowframe and will under all conditions tend to align itself so that theslots are retained at all times in proper operative position relative tothe blind.

Another object of this invention is to provide a guide member which willnot bind on the shade or cause the looping of the shade above themember.

Still another object of this invention is to provide a handy stop memberlimiting the upward movement of the blind.

And another object of this invention is to provide a device of thischaracter in which the operative portion of the device is spaced fromthe attaching means therefore, fraying of the edges of the blind beingthus prevented and the device is made generally more versatile inapplication.

And a last object to be specifically mentioned is to provide a windowshade guide in a form making the same inexpensive and practicable tomanufacture, extremely simple to install and use, and which will begenerally efiiclent and durable in service.

With these and other objects in view as will appear hereinafter, thisinvention resides in certain novel features of construction, combinationand arrangement of parts as will be hereinafter described in detail andparticularly set forth in the appended claims, reference being had tothe accompanying drawings which form a material part of thisapplication, and in which:

Figure 1 is a front elevational view of a window frame, sash and blindwith a pair of devices designed according to this invention appliedthereto in operative position;

Figure 2 is a vertical sectional view of this invention and a contiguousportion of a window blind used therewith, the view being essentiallytaken on the line 2-2 in Figure l; and

Figure 3 is an enlarged fragmentary view of contiguous portions of awindow frame and a blind with this invention operatively appliedthereto, the shade being shown in elevation and the other portions ofthe figure being shown in vertical section.

Similar characters of reference designate similar or identical parts andportions throughout the specification and throughout the views of thedrawings.

Referring now to the drawing, which illustrates a preferred embodimentof this invention, a window frame Ill having a window sash I2, isprovided with a window shade l4 mounted on a roller l6 at the top ofsaid frame according to conventional design and here represented inorder to show the environment wherewith this invention is adapted to beused.

This invention contemplates the provision of flat discs or plates l8,centrally apertured to receive an attaching screw 20 whereby this flatplate is firmly secured to the window frame I 0 as hereinafterdescribed. Integral with said plate l8 and extending normally from oneside thereof is a hollow cylinder 22. The end of the cylinder 22, remotefrom the attaching screw 20, is provided with diametrically disposedslots 24 and 26, these slots being slightly wider than the thickness ofthe shade wherewith they are to be used, and extend to points 28 and 30intermediate the ends of the cylinder. It is preferred that the edges ofthe slotted portions be beveled to lessen the tendency of the device tofray the edges of the window blind l4.

Obviously, the plate l8 need not be circular and the size of this platemay be considerably greater than the base portion of the member 22. Itwill also be understood that the cylindrical form of the member 22 ishere used illustratively and other shapes being used, the essentialfeature of this invention is the provision of a hollow member havingwalls which may be slotted to provide two spaced shade contactingmembers, the mem-- her being essentially hollow in order to provide forthe convenient mounting of the device by a screw 20. It would, however,be within the province of this invention to extend the plate 18 beyondthe periphery of the member 22 and to secure the device in position on awindow frame by means of screws inserted through the extending portionof the plate.

In using this device the upper limit to which the blind will normally beraised must be predetermined and' the devices are-placed-one on eitherside of the blind, with the edges of the blind inserted in the slots 24and 26, the attachment of the devices to the window frame -10 being, ofcourse, achieved prior to the insertion of the blind in the slots. Infunctioning asca stop member the upper edge of the reinforced lower end32 of the blind abuts the lower surfaces of the members 22, effectuallyapreventing the raising of the blind beyond the devices. The

5 Having thus described this invention what is claimed as new anddesired to be secured by Letters Patent is:

A device comprising a base securable to a window casing and a hollowmember extending 'from:onerfacev.of said base having-two, diametrically-disposed parallel slots in the walls thereof adapted to receive oneedge of a window shade,
